Understanding Thyroid Cartilage: Structure, Function, and Common Disorders
The thyroid cartilage is one of the most crucial structures in the human neck, serving as a protective shield for the vocal cords and playing a significant role in speech production and breathing. Commonly recognized as the “Adam’s apple” in males, this cartilage is part of the larynx and is made of hyaline cartilage. While its primary function is to support the voice box, the thyroid cartilage can be affected by various medical conditions, including fractures, inflammation, and age-related ossification.
In this blog, we will explore the structure, function, and common disorders associated with the thyroid cartilage, along with essential tips to maintain its health. If you experience any issues related to your voice or breathing, seeking professional medical advice is crucial.

What is Thyroid Cartilage?
The thyroid cartilage is the largest cartilage of the larynx (voice box) and plays a vital role in protecting the vocal cords. It is commonly known as the “Adam’s apple” in males due to its prominent external structure. This cartilage is made of hyaline cartilage and is essential for voice modulation and airway protection.
Structure and Anatomy of Thyroid Cartilage
The Adam’s apple consists of two large plates called laminae, which meet at an angle to form the laryngeal prominence. In males, this prominence is more pronounced due to the effects of testosterone during puberty. The cartilage provides attachment points for several muscles and ligaments that aid in speech and swallowing.
Key Features of Thyroid Cartilage:
- Laryngeal prominence: The noticeable protrusion in the neck, particularly in males.
- Superior and inferior horns: These connect to the hyoid bone and cricoid cartilage, providing stability.
- Attachment site: It serves as an anchor for the vocal cords and surrounding muscles.
Function of Thyroid Cartilage
The thyroid cartilage has several essential functions in the human body:
1. Protection of Vocal Cords
It shields the vocal cords from external trauma and damage, ensuring smooth voice production.
2. Voice Production
By serving as an anchor for the vocal cords, the Adam’s apple plays a key role in sound modulation and pitch control.
3. Airway Support
It keeps the larynx stable and supports normal breathing by preventing airway collapse.
4. Swallowing Mechanism
During swallowing, the thyroid cartilage moves upward to prevent food from entering the airway.
Common Disorders Associated with Adam’s apple
Several medical conditions can affect the Adam’s apple, leading to discomfort, voice changes, and breathing difficulties.
1. Adam’s apple Fracture
A direct impact on the neck, such as in accidents or sports injuries, can cause fractures in the Adam’s apple. Symptoms include difficulty breathing, pain, and changes in voice.
2. Laryngitis
Inflammation of the larynx can affect the Adam’s apple, leading to hoarseness, sore throat, and difficulty speaking.
3. Thyroid Cartilage Ossification
With age, the thyroid cartilage may ossify (turn into bone), leading to stiffness in the larynx and voice changes.
4. Thyroid Cartilage Tumours
Though rare, tumours can develop in or around the thyroid cartilage, causing swelling, pain, and difficulty swallowing.
Diagnosis and Treatment of Thyroid Cartilage Disorders
Medical professionals diagnose thyroid cartilage disorders using imaging techniques such as X-rays, CT scans, and laryngoscopy. Depending on the condition, treatment options include:
- Medications: Anti-inflammatory drugs or antibiotics for infections.
- Voice Therapy: Helps restore normal vocal function.
- Surgery: In severe cases, surgical intervention may be required.

How to Keep Your Thyroid Cartilage Healthy?
Taking care of your thyroid cartilage can prevent many disorders. Here are some tips:
- Stay Hydrated – Drink plenty of water to keep your vocal cords and larynx moist.
- Avoid Smoking – Smoking can irritate the larynx and cause inflammation.
- Use Your Voice Wisely – Avoid straining your voice with excessive shouting or whispering.
- Practice Neck Safety – Protect your neck from injury during physical activities.
- Seek Medical Help for Persistent Hoarseness – If you experience prolonged voice changes, consult an ENT specialist.
Conclusion
The thyroid cartilage is an essential structure in the human body that supports voice production, breathing, and swallowing. While it is robust, it can be affected by various conditions that may require medical intervention. If you experience any symptoms related to thyroid cartilage disorders, it is best to consult specialists at Lifeline Hospital, Adoor, Kerala’s leading multispecialty hospital, for expert care and treatment.
